libceph: clear messenger auth_retry flag when we authenticate

Browse source 
commit 20e55c4cc7 upstream.

We maintain a counter of failed auth attempts to allow us to retry once
before failing.  However, if the second attempt succeeds, the flag isn't
cleared, which makes us think auth failed again later when the connection
resets for other reasons (like a socket error).

This is one part of the sorry sequence of events in bug
